Use shell in linux to monitor website status

Our website now uses some tools to monitor whether the website server can be accessed, but not the status of the website. Next I will recommend you to use shell to monitor the website status script in linux.

Today, I wrote shell monitoring for my website, so I don't know if my website goes down. This script checks the webpage status and webpage connection time separately, and can be expanded as needed, very powerful.
Script content:
Vi check-web.sh

The Code is as follows:

Copy code

#! /Bin/sh Weblist =/root/weblist.txt For list in 'cat $ weblist | grep-E-v "# | ^ $ "' Do Httpcode = 'curl-o/dev/null-s-w % {http_code} "$ list "' Httptime = 'curl-o/dev/null-s-w "time_connect: % {time_connect} ntime_starttransfer: % {time_starttransfer} ntime_total: % {time_total} n "" $ list "| grep time_total | awk-F": "'{print $2*1000 }'' # If [$ httpcode = 200] | [$ httpcode = 301] | [$ httpcode = 302] | [$ httpcode = 403] | [$ httpcode = 401] If [$ httpcode = 200] | [$ httpcode = 301] | [$ httpcode = 302] Then Echo "$ list is checked OK! " Else Echo "$ list is down! "| Mutt-s" web is down "rocdk@163.com Fi If [$ httptime-ge 10000] Then Echo "$ list is timeout! "| Mutt-s" web is timeout "rocdk@163.com Else Echo "$ list is connect OK! " Fi Done

Then create a list of websites to check, in the http://xxx.xxx.xxx format

The Code is as follows:	Copy code
Touch/root/weblist.txt Http://blog.slogra.com Chmod + x/root/soft_shell/check-web.sh Crontab-e */3 */bin/sh/root/soft_shell/check-web.sh

The following figure shows the manual operation.

Okay, you can rest assured.
